    Default [SOLVED] unable to send mail to external domains

    I have setup ZCS on Ubuntu 7.04 with public IP successfully and am able to receive emails to my @example.com from external domains.

    I am getting
    Code:
    Message not sent; one or more addresses were not accepted.
    Rejected addresses: <emailaddress@domain.com>
    However I am not able to send emails via Web-client to gmail or yahoo mail. I am able to send emails within my domain?

    Why wont Zimbra by default send emails to external domains?

    Am using OpenDNS on Zimbra Server.

    Any help will be much appreciated.

    Code:
    postconf mynetworks
    mynetworks = 192.168.0.32/27
    my local machine is 192.168.0.40

    so now i have given
    Code:
    zmprov modifyServer mail.bksec.co.in zimbraMtaMyNetworks '127.0.0.0/8 172.16.1.0/24 192.168.0.32/27'
    postfix reload
    and am getting:
    Code:
    postconf mynetworks
    mynetworks = 127.0.0.0/8 172.16.1.0/24 192.168.0.32/27
    172.16.1.0 is the secondary IP (internal) for the Zimbra server.

    Yeah it works now. But still have one setting to test. Because its a web client i assume I dont have to give my local network IP.

    You probably want to add
    Code:
    192.168.0.0/24
    instead of the single IP you've put in there so your LAN users can relay through the server, web mail would be OK but not if the used a fat client like Thunderbird.

    Thanks for all the fantastic and super-fast response!

    thats not a single IP. Thats a segmented LAN. The range is 192.168.0.33-62.
    So I need to add all local networks according to the subnet, right? (not just 192.168.0.0/24 to have all 254 computers?)

    thanks.

    one simple question.
    can i have a 2nd zimbra server just send emails. Basically load should be shared between two mail servers (one to send and one to receive). We have about 350+ users.

    Sure it's called a multi-server setup, you could put the LDAP & Mailstore etc on one box & the MTA on another.
    You can do all sorts of things - this is way more than you need but it's a good example:


    You can check out all the guides at: /products/documentation.html or /community/documentation.html

    Sorry, I was daydreaming there. Yes, you can have a segmented LAN if you choose or the complete subnet - whatever fits your set-up.
